Chapter 14: Muscles, Bones, and Skin



Chapter 14: Muscles, Bones, and Skin Study Guide

Question 23 does not require an answer

1. List the organizational system of organisms from cells to organisms - cells, tissues, organs, organ systems

2. Define: Bone, Ligament, Tendon, and Cartilage

Bone – complex living structures that undergo growth and development.

Ligament – strong connective tissue that hold bones together at joints.

Tendon – connective tissue that attaches muscle to bone.

Cartilage – connective tissue more flexible than bone.

3. Identify the 5 main functions of the skeletal system.

Movement, protection, support, storage, & producing blood cells

4. Differentiate between an immovable and movable joint. Immovable allow little of no movement like the bones of the skull. Movable joints allow the body to make a large range of movements.

5. Identify an example of an immovable joint.skull

6. Identify the 4 main types of movable joints, describe the action of each, and list an example of each joint.

Hinge – backward and forward – knee

Ball and Socket – greatest range in a circle – shoulder

Pivot – Rotate around another bone – neck

Gliding Joint – Sliding - wrist

7. List at least 4 characteristics of the muscular system.

• Muscles can contract

• Some are voluntary some are involuntary

• Exercise maintains strength and flexibility

• Allow movement of the body

8. Differentiate between a voluntary and involuntary muscle movement.

Voluntary – you consciously control

Involuntary– occur without your conscious control

9. Identify the muscle movement for each of the types of muscle.

Skeletal – voluntary

Smooth - involunary

Cardiac- involuntary

10. What muscles tire easily? What muscles have a quick reaction?.skeletal; skeletal

11. Why do skeletal muscles work in pairs?because muscle cells can only contract not extend

12. Explain the statement, “Muscles only pull, never push.”they can only pull the bone when the contract, cant extend and push a bone

13. How does the skin protect the body from disease?it forms a barrier between the inside and outside of the body

14. In which layer of the skin would you find nerves and blood vessels.__dermis_________

15. Define homeostasis?__body’s ability to maintain stable internal conditions despite external conditions ____________

16. Your internal body temperature will always be about __37____C

17. What is the function of melanin besides giving the skin pigment (color)?_____protect skin from burning_______________________________________

18. How does the skin help regulate body temperature?____sweat glands and perspiration____________________

19. Dairy products are good for your bones because they contain the mineral _calcium_________ which helps prevent osteoporosis.

19. Another name for the cranium is the _skull______________.

20. A baby’s skeleton is made of mostly ____cartilage_______________.

*21. You must be able to label the 21 bones of the skeleton. Practice below :

22. Draw a picture of cardiac, smooth, and skeletal muscle below (pg. 483)

23 You must be able to label specific muscles: biceps, deltoids, quadriceps, gluteus maximus, triceps, pectoral muscles, sartorius, and gastrocnemius
